SPECIFICATION forming part of Letters Patent No. 490,198, dated January 17, 1893.

Application filed March 31, 1892. Serial No- 42'7,212. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS B. HARVEY, a citizen of the United States of America, residing at Atglen, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Harrows and Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in combined barrows and rollers.

The object of theinvention is to provide a barrow frame to which rollers are attached of such construction that the barrow may be raised to free it from dbris or when it is de sired to transport the same without causing the teeth to enter the soil; such a harrow and roller being provided with a seat and means for elevating or depressing the harrow frame either from the seat or ground; and the invention consists in the construction and combination of the parts, as will be hereinafter in the claims.

In the accompanying drawings forming part of this specification: Figure 1 is aperspective view showing the invention arranged in a position for use. Fig. 2 is a side elevation showing the barrow. frame elevated so that the teeth will be out of contact with the soil. Fig. 3 is a detail view of a spring tooth.

A designates the harrow frame, which is made up of two transverse sections centrally connected to each other by hinges a a, the leaves of which are attached to the undersides of the beams A forming part of the harrow sections. The longitudinal beams A carry the harrow or cultivator teeth. The

harrow frame is also provided with a transverse bar a, which is hinged centrally and rigidly secured to the beams A B B designate bars which extend from the corners of the barrow frame and to which the rollers O G are journaled, said bars being pivoted by means of bolts?) to the side beams A. The inner ends of these bars are provided with segmental slots,b, through which pass headed bolts 1) into the side beams. Each pair of bars B B is connected to each other by scrapers the ends of which are bent and aperturcd for the reception of bolts which pass through slots (Z in the bars adjacentto the rollers, so that said scrapers can be adjusted to and from the rollers. These scrapers are further braced by straps or connections D, which extend from the center of the scraper to the beams A at which point they are slotted to receive the proper adjustment.

E designates a l6V6l,Whl(3l1 is suitably bent at its lower end and passes through a bifurcated standard e in which it is free to slide, the forward part of said lever passing through loops 6 and 6 carried by the center beams of the harrow sections. The loop or guide 9' is comparatively near the forward end of the central beam carried by the rear harrow section, while the loop e is some distance from the end of the opposite beam. This lever has a notch f located in advance of the bifurcated standard with which the bent end of a bifurcated rod F is adapted to engage, and when said rod is in engagement with the lever the bent end thereof will prevent said lever being operated. By drawing the lever rearward it can be disengaged from the loop 6 and when so disengaged by depressing upon the rear end of the lever the barrow sections may be elevated to the position shown in Fig. 2 of the drawings so as to relieve the teeth from any dbris or trash which may have caught thereon. When it is desired to keep the harrow sections elevated, as in transporting the barrow and roller, the hooks or rods G carried by the side beams A are caused to engage with each other, as shown in Fig. 2.

H designates the draft pole or tongue,which is connected by means of strips h h to the bars 13 B located at the forward end of the harrow.

With the parts hereinbefore referred to it is not essential to employ the hinged strip a; but said strip serves a useful purpose in connection with the seat I or foot rest K, which parts I will proceed to describe. The seat I is supported by the front standardst Lwhich are pivotally connected to brackets secured to the beam A of the harrow frame and are rigidly secured to the seat. The rear standards, '21 t", are pivoted at their upper ends to 'theseat and at their lower ends to brackets rigidly secured to the rearbeam A Byproviding pivotal connections as shown the harzrow sections may be raised or lowered and 1 a the members of the hinged rod a.

the seat remain in a horizontal position.

The foot rest K is pivotally connected to V the seat standards by means of the crossbar Z and normally rests upon. a raised support L'attached to thefrontbeam Ad. This with a rod N pivotally' connected to' one of The foot rest also carries a standard m, which the operator can grasp to steady himself when he stands on the frontend of the foot-rest to use his weight to .tilt said foot-rest and elevate the harrow'sectionsflhe snppo'rtL acting as a fulcrum'and the lever m being operated at the same time. Byiresuming his seat and releasing the lever-1m theoperator will bring E theharrow to its'normal position cured in any suitable manner to the longi- The standard 0. of this 1 tooth extends down below the plane of the; wings p, and this extension 0 of the tooth is 1 tudinal' beams A narrow and enters the soil before the wings do, and entering'the soil to a greater depth than the wings serves to keep the tooth steady and preserve the proper line'of draft when in 'Each tooth is provided with rearwardly projecting wings p, which incline from their rear edges downward and are bent slightly at their'ends where they are to provide the rearward extensions 1?. The ends of thewings of the teeth are slightly elevated and effectively pulverize the earth, and by such construction the earth is not thrown beyond the track of the teeth but is thrown toward the center portion thereof. The tooth described is attached to the barrow frame preferably as described in my prior patent dated June 10,

1890, in which the teeth are pivotedto theI harrow frame so as to turn laterally upon their pivots, said teeth having rearwardly diverging wings with extended portions adjacent to the rear ends thereof. The tooth in the present instance differs in what the front portion is comparatively narrow and has a front cutting and guiding portion with wings having inwardly bent ends.

Rdesignates a spring tooth which may be attached to the harrow frame instead of the style or form of tooth shown in Figs. 1 and 2 of the drawings. The upper portion of this spring tooth is of ordinary construction, and to near the lower portion of the same, by a bolt 7", is attached a spring plate S, which is bifurcated at its lower end; the furcated portions thereof being extended rearwardly and downwardly to form members 3 having upwardly turned ends 3 which act upon the soil in the same manner as the members p and 9) of the style of tooth shown in Figs. 1 and 2.

will operate in the soil the same as the point 0'. Rear of the plates is secured areinforcwears away. This plate willhold the part having the diverging wings firmly against the spring tooth and prevent rearward movement and rear rollers, substantially as shown and In connection with the barrow hereinbefore 3 describedl employ teeth, 0, which are sefor the'purposeset forth. 7
